Above-mentioned U.S. Pat 6,027,701 described discharge cells comprise ground electrode, insulation tube and high voltage electrode, and order from inside to outside is high voltage electrode, discharging gap, insulation tube and ground electrode.Wherein the outer wall of insulation tube and ground electrode fuse together by means such as fusion, welding, the advantage of this structure is that insulation tube and ground electrode fuse into one and is very close to each other, but its complete processing requires and manufacturing cost is higher, in case and Glass tubing breaks or breakdown, discharge cell can not be changed permanent failure.Therefore it need a kind of good heat dissipation effect, low cost of manufacture and be easy to the discharge cell installing, change.
Summary of the invention:
The object of the present invention is to provide a kind of good heat dissipation effect that is used for ozonizer, low cost of manufacture and be easy to the discharge cell installing and change.
The present invention realizes like this, a kind of discharge cell that is used for ozonizer, comprise each one of ground electrode, insulation tube and high voltage electrode, wherein high voltage electrode adopts conductive material, ground electrode ground connection, described discharge cell also comprise a discharging gap, and described discharging gap is arranged between high voltage electrode and the insulation tube, the outside surface of insulation tube is covered with a conductive metal layer, described conductive metal layer ground connection.
For the life-span that prolongs high voltage electrode is covered with the layer of metal oxide film at its outside surface and is used to prevent that high voltage electrode is worn out by ozone and discharge corrosion.
In order to reach better heat radiating effect, be preferred version for gapless the cooperation between insulation tube and the ground electrode.
The discharge cell that the ozonizer of employing technical solution of the present invention is used has following advantage:
1. ground electrode and insulation tube are to closely cooperate but two separate elements, under breaking situation, removes insulation tube damaged insulation tube easily, and only need suit insulation tube in ground electrode and need not to change intact ground electrode, economize on resources, and it is convenient to install and change, and effectively reduces maintenance cost;
2. the insulation tube outside surface is covered with one deck conductive metal layer, and the conductive metal layer ground connection of insulation tube outside surface, so just can guarantee does not have voltage difference between insulation tube outside surface and the ground electrode, even closely do not exist the gap electric discharge phenomena can not take place because of cooperating between insulation tube outside surface and the ground electrode yet;
3. be gapless the cooperation between insulation tube and the ground electrode, the heat of discharge generation can easily distribute to outside surface by insulation tube and ground electrode;
4. the insulation tube adopting quartz glass is difficult for breaking, the little and good heat dissipation effect of dielectric loss;
